Hi yall, got a 2010 g37 now at 100k km living in a dry hot city
My dealer never did any maintenance on the roof system
last week I popped the roof open twice and I noticed it stops mid cycle and beeps few times and just keeps going
I am wondering if I need to do some form of maintenance whether fluids or arms or anything.

 

They're are some grease points in the FSM, but also there are diags at the dealer to read the code it's throwning.
